- CANDLE-MOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 755,892, dated March29, 1904.

Application filed October 22, 1903.

To all whom it may concern.-

Be it known that I, SETH H. LEAVENWORTH, a citizen of the United States,residing at Cincinnati, in. the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Candle-MoldingMachines, of which the following is a specification.

My invention relates to a machine for forming wax candles, and moreparticularly those having a tapered base and known to the trade asself-fitting-in candles.

The features of my invention are more fully set forth in the descriptionof the accompa nying drawings, forming a part of this specification, inwhich Figure 1 is a view of two molds, showing one in section and one inside elevation. Fig. 2 is a line on w as, Fig. 1. Fig. 3 is a plan viewillustrating the release mechanism. Fig. 4 is a section on line w w,Fig. 1, showing the mechanism for actuating the release. Fig. 5 is adetail view, partly in section, of a modification of the mold liftingand depressing mechanism.

A represents the floor of the tray for receiving and feeding the moltenmaterial to the molds, and A the bottom.

B represents the molds. Formed on the'bottom are the supporting-caps B,having screw- 'threaded engagement with the floor A of the machine.

B represents nuts screw-threaded onto the under projecting portions ofthe parts B to secure the molds in upright position.

C C represent the plungers within the molds for expressing the candlestherefrom. They are supported upon the vertically moving cross-head D.

Seated upon or attached tothe top ends of the molds B are the topsupporting-caps'B having screw-threaded engagement with the upper framemember A. These top caps I?) are provided with openings of greaterdiameter than the internal diameter of the moldsB.

E represents the mold for forming the fancy base of the candle. Thesetop molds fit within the openings of the caps B The top molds E arecomposed of the half-sleeves F F. H H

represent vertical tubes, one upon each side of position.

Serial No. 178,077. (No model.)

the molds B, which tubes pass through the lower supporting-caps B. andwhich engage through the bottom sections of the upper supporting-caps B(See Fig. 1.) Through these tubes pass the actuating-rods I I, whichrods are at their lower ends supported upon the vertically-movablecross-head J. The upper end of the actuating-rod I is fixed to one sideof the I half-sleeve F, the other rod I being fixed to the Theactuating-rods I I fulcrum in their re- I spective tubes H H. To thelower ends of these actuating-rods, above the cross-head J, are

fixed the rocking arms a a a a, the other ends of said arms beingpivoted to the operatinglever K.- (See Figs. 1 and 4.) In stating thatthe actuating-rods are fixed to the halfsleeves at the top and therocking arms at the bottom I mean they turn together.

In molding the parts are in the initial position (shown in the sectionalview in Fig. 1,) the molten tallow or wax being introduced from the topin any approved manner. When the candle is formed, the cross-head J israised, which lifts the top molds E from the supporting-caps B to aposition above the top frame A. The lever K is then actuated to turn therods I I, thereby pivotally swinging the halfsleeves on their respectivepivots to the open (Illustrated in dotted lines, Fig. 3.) The candle canthen be readily expressed by raising the cross-head D. By turning thelever K in the opposite direction the half-sleeves are again broughttogether and can be lowered into the openings of the supporting-caps Bhalf-sleeves are coupled, I preferably employ some form of interlockbetween the meeting ends of said half-sleeves, preferably employing thedovetail formation 6 b. (Illustrated in dotted lines, Fig. 3.)

The simplicity of this device and its full performance of the desiredfunctions are obvious, and I do not desire to be limited to the preciseform of actuating mechanism for actuating the half-sleeves where obviousequivalents may be substituted therefor.

In Fig. 5 I show a modification of the mounting of the actuating-rods Ion the crossl1ead J. The arms a are provided with square orifices toreceive the squared sections Z2 on the lower part of the rods I. Thissquared section of the rod I passes through and extends below thecross-head J and is provided with the adjusting-nut c on the lower end.0? represents a coil-spring around the lower end 6 of the rod I, one endof the spring engaging the nut 0, the upper end of the spring engagingthe under side of the cross-head J. The cutting out of the sides I tomake the square portion 6 produces the shoulders e. In raising thecross-head J it is evident that the arms a will engage the shoulders eof the rod I and lift the same. In depressing the molds E into theopenings of the caps B if any foreign substance or material should getlodged between the mold and the cap it is evident that when thecross-head J would be pressed it would carry downward uniformly all ofthe rods for raising and lowering the molds excepting the particularmold or molds that might, happen to be caught up, the coil-springs d andthe particular formation described and shown in Fig. 5 permitting onemold to remain elevated while the others are depressed. With thisarrangement when any one mold gets clogged it does not hold them all up,as would result if the rods were rigidly attached to the crosshead. Asonly the particular mold which is clogged remains elevated it serves toindicate the source of the trouble as well as limiting the trouble tothe particular mold involved.

Having described my invention, I claim 1. In a machine for formingtaper-base candles a mold formed of half-sleeves, the opposite ends ofsaid sleeves being fulcrumed, and means for swinging said half-sleeveson their fulcrums, whereby the swinging end of one half-sleeve engagesand disengages the fulcrumed end of its cooperating sleeve,substantially as specified.

2. In amachine for forming taper-base candles a mold formed ofhalf-sleeves, the opposite ends of said sleeves being fulcrumed andmeans for swinging said half-sleeves on their fulcrum, whereby theswinging end of one half-sleeve engages and disengages the fulcrumed endof its cooperating sleeve, the said sleeve being formed withinterlocking ends, substantially as specified.

3. In a machine for forming tapeiwbase candles a stationary mold for theuniform bodysection thereof, a mold for the taper base consisting ofhalf-sleeves, the opposite ends of said sleeves being fulcrumed andmeans for swinging said half-sleeves on their fulcrum, whereby theswinging end of one half-sleeve engages and disengages the fulcrumed endof iitsdcooperating sleeve, substantially as speci- 4. In a machine forforming taper-base candles a mold formed of half-sleeves, anactuating-rod fixed to the opposite end of each halfsleeve and means forracking the said rods in opposite directions whereby the swinging end ofone half-sleeve engages and disengages the fulcrumed end of itscooperating sleeve, substantially as specified.
